Packing label cover to be used at the time of record cleaning was exchanged since the deterioration. You can use without any problems, but escapes to the outside when the yelling tightening, may prefer another smaller one size inner diameter was good?

My measurement mistake it did not have enough little thickness. It is too thick in the 5 and 7 mm, but I noticed that there was a 3,1 mm I checked well after. Shipping will be saved is that it is e-mail facilities.
